Data on the effects of repeated disturbances in aquatic bacterioplankton communities

Disturbances are believed to be one of the main factors influencing variations in community diversity and functioning. Here we investigated if exposure to a pH press disturbance affected the composition and functional performance of a bacterial community and its resistance, recovery and resilience to a second press disturbance (salt addition). Lake bacterial assemblages were initially exposed to reduced pH in six mesocosms whereas another six mesocosms were kept as reference. Seven days after the pH disturbance, three tanks from each treatment were exposed to a salt disturbance. See "Repeated disturbances affect functional but not compositional resistance and resilience in an aquatic bacterioplankton community" by Sjöstedt et al (2018) for furhter information. The dataset was originally published in DiVA and moved to SND in 2024.扰动被视作影响群落多样性与功能动态变化的核心驱动因素之一。本研究旨在探究：经pH持续扰动（pH press disturbance）暴露后，细菌群落的组成与功能表现是否会发生改变，同时探究该群落对第二次持续扰动（盐添加）的抗性、恢复能力与弹性是否受到影响。研究中将6个中型实验生态系统（mesocosms）内的湖泊细菌聚群（Lake bacterial assemblages）置于低pH环境中进行暴露处理，另外6个中型实验生态系统作为对照处理组。在pH扰动施加7天后，每个处理组中的3个实验单元均接受盐扰动暴露处理。 如需进一步了解详情，请参阅Sjöstedt等人2018年发表的论文《重复扰动对水生浮游细菌群落功能而非组成抗性与弹性的影响》。 本数据集最初发布于DiVA平台，并于2024年迁移至SND平台。
